To all whom it may concern.-

Be it known that I, FRANZ CECKA, a citizen of the German Empire, residing at Chemnitz, Germany, have invented certain new and useful Improvements in Apparatus for Making Reinforced Knitted Goods; and I do hereby deglare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to .the accompanying drawings, and to letters orfigures of reference marked thereon, which forma part of this specification.

My invention relates to improvements in.

a method of and apparatus for making reinforced knitted goods.

In the manufacture of knitted goods it is usual to loosen the loops when making reinforced parts, in order to impart suflicient elasticity to the reinforced parts. If the reinforced parts. were made with the same close loops as the parts which are not reinforced, the goods would be close and unelastic in the reinforced parts) In order to loosen the loops the knitting depth of the frame is increased by rocking the needle bar so asto produce loops of increased length, for which purpose the known loosening and closingca'm is set at the beginning of the operation so'as to produce for a definite part of the aggregate stroke of the thread guide a different knitting depth.

The object of the improvements is to provide a method of and an apparatus for knitting reinforced goods by means of which fashioned reinforced-parts can be produced, i. 6. reinforced .parts which are of varying breadth. Y

With this object in view my invention consists in the matters to be-described hereinafter and particularl pointed out in the appended claims, re erence being had to the accompanying drawings .and to the In said drawings. Figure 1 is a diagram- 7 matical view showing. aknitting'apparatus heel and toe portions of "a knitted stocking prior .to unitin the sides of the same, the

reinforced 'portions having the forms now in use, Figs. 4 and 5,, are similar views showing goods in which the reinforced portions are made according to my improved method, Fig. 6, is a view of a mechanism suitable for making reinforced goods according to my improved method, and Figs. 7 cross-sections taken respectively on the lines AB and CD of Fig. 6.

The same letters of reference have been used in all the views to indicate corresponding parts.

Referring to Figs. 2 and 3, in the manufacture of the cross-hatched jparts 'F of the heel and S of the-toe the length of the loops is increased over the whole breadth of the head of the frame. However, if it is desired to make a reinforced ankle H, as is shown in Fig. 2, or a double sole D,.-as is .shown in Fig. 3, a part only of the breadth 0-d are not reinforced. In such cases the knitting depth is pressingtheneedle bar N from the position length of the loops.

of cams 8 and 10, mounted on a shaft 1. As

the distance 22 0f the said cams 810 is constant, the border lines 1-2 and 1-2. of. such reinforced portions are-straight, as is shown in Figs. v2 and 3. The breadth c.d and (f-d between the reinforced portions can be set before the operation, but it can not be changed in the course of the manufacture of thegoods. the reinforced parts are always made by the same needles of the head of the frame While for the proper comprehension of the object of the present invention the diagrammatical showing of theoperating connection of the needle bar N, as givenin Fig. 1-, is

obviously sufficient, the real relation of the parts and their proper cooperation may be ascertained by reference to Fig. 1", in which 41' designates the ordinary actuating cam for the needle bar N. The-cam 41 issecured upon the shaft 1 and controls. a bowl 42 car-- ried by an arm 52 which with its shaft 47 is mounted to be able 'to'oscillate. The needle bar N is adapted to swin 45 and about the shaft 46, and is operativelyconnected to the. said rocking arm 52 by If the actuating and 8, are

temporarily varied by so as to increase the T1118 is done by means on the pivots The border lines of- I 50. The latter shaft 50 is different needles.

cam 41 moves the bowl 42 radially outward, the rocking arm 52 will thereupon cause the needle bar. N to swing toward the presser bar P as indicated by the arrow II. Upon the said shaft l there are mounted the cams 8 and 10 above described as producing the required additional movements of the needle bar for temporarily increasing the length of the loops to be formed. For this purpose the cams 8 and 11) are adapted to cooperate with a bowl 49' carried at the end of an arm 49, which is secured upon a rocking shaft second arm 51 adapted to engage an exten sion 52 of the arm 52 controlling the operation of the needle bar N.

When by any suitable means the bowl 49 is shifted into the path of action of the loop loosening cams 8 and 10, the needle bar N will then be controlled by the said loop loosemng cams 8 and 10 and moved according to the extent of the strokes of the latter.

By means of apparatus of this class such reinforced goods can not are provided with fashioned reinforced portions, such as are shown for example in Figs. 4 and 5, where not only the breadth, but also the inner border lines of the reinforced portions are changed and made by Therefore the apparatus can be used only in such cases in which a reinforced portion is 'to be produced which begins in definite rows of loops and which is not changed in the course ofthe operation. But where fashioned reinforced portions are to bemade in which the breadth is increased or reduced in the course of the manufacture the apparatus can not be used.

In order to obtain a variation of the knit ting depth which corresponds to the desired form of the reinforced portions the cams of the loosening and straightening cam are so mounted relatively to each other that their relative position can automatically be changed while the machine is in operation, so that the eflect of the ca-msand the setting of the needle bar caused thereby and the variation of the knitting depth can be performed in the successive rows of loops at different points. Thereby I am enabled to produce reinforced portions which are gradually increased or reduced, such as is shown by way of example in Figs. 4 and 5. The cams are set in a suitable way by means of a jacquard card or a counting mechanism ac-,

cording to the desired form of the reinforced parts. Thereby I am also enabled to produce reinforced portions of uniform breadths in narrowed or widened goods.

In order that my invention be more clearly understood mechanism for putting the same into effect has been shown by way of example in F igs. 6 to 8. As shown inthe said figures, a shaft 1 carries a disk 2 the hub 3 'of which provides a loose support for disks provided with -a be made which '12 are mounted. On the shaft Y11 and at one side of the disk 2 a gear wheel 13-is mounted which is inmesh with the rack teeth 7 and at the opposite side of the disk 2 a gear wheel 14 and a ratchet Wheel 15 are secured to the shaft 11.

To-the shaft 12 a gear wheel 16 and at the opposite side of the disk 2 a gear wheel 17 and a ratchet wheel 18 are secured. The gear wheels 14 and 17 are in mesh with each other.

On a pivot bolt 19 of the disk 2 an arm 20 has a rocking support which projects beyond the disk 2 and is acted upon by a spring 21, and to the said .arm a pawl 22 is jointed which is in engagement with the ratchet wheel 15. On a second pivot bolt 23 a similar arm 24 has a rocking support which is acted'upon by a spring 25, and- The lever 28 is in the path of the arm 20 and the lever 29 in the path of the arm 24.

On a pivot-bolt 32 a bell crank lever'33 is mounted which acts on the lever 28, and on a pivot bolt 34 a bell crank lever 35 is mounted which acts on the lever 29. To the free ends of the said levers links 36 and 36 are jointed.

The operation of the mechanism is as follows: The links 36 and 36 are controlled by suitable" means such for example as a jacquard card or another counting mechanism. For example, if the link 36 has been drawn'to the right as is shown in Fig. 6, the bell crank lever 33 connected therewith forces the shift. lever 28 forward and in opposition to the spring 30 and into posi- 14 are rotated, and the gear wheel 13 which is in mesh with the rack teeth 7 of the disk 4 moves the'cam 8 awayfrom the cam 10.

As the gear wheel 14 is in mesh with the gear wheel 17 also the gear wheel 16 is rotated which is in mesh with the teeth 9 of the disk 5 carrying the cam 10, so that the said cam is moved in a direction opposite to that of the cam 8.

Therefore the in-'. crease of the distanceof the cams 8 and 10 corresponds to the double shifting movemlel-ntlimparted by the pawl 22 to the ratchet w ee Whenever the bell crank lever'33 forces the shift lever 28 forward upon each rotation of the shaft 1 the distance of the cams 8 and 10 is increased, so that in the blank being knitted the breadth of the portion which is not being reinforced is enlarged, because the movement of the needle.bar causing the increase in the knitting depth ceases at an earlier moment and begins later. If on the other hand it is desired to reduce the 'portion which is not to be reinforced, the bell crank lever must be moved by the counting mechanism. Thereby the shift lever 29 located in the path of the arm 24 is rocked forward, so that upon rotation'of the shaft 1 and the disk 2 the arm 2% is rocked and the pawl 26 mounted thereon acts on the ratchet wheel 18, which carries along the gear wheels 16 and 17. The gear wheel 16 engages in the teeth of the rack teeth 9 of the disk 5 and shifts the cani 10 mounted on said disk toward the cam 8. Simultaneously the gear wheel 17 rotates the gear wheels 14 and 13 and through the latter the disk 4 and the cam 8 mounted thereon, so that now both cams are shifted relatively to each other a distance corresponding to-the double path of the ratchet wheel 18.

By providing a 1acquard pattern or selector or. controlling mechanism of the and the end of the change of the knitting depth can be varied as is necessary for obtaining the desired form of'the reinforced part.

While in describing the invention reference has been made to a particular example embodying the same, I wish it to be understood, that my invention is not limited to the general arrangement and construction of the the desired knitting parts shown in'the figures. For example, the mechanism forsetting the cams 8 and 10 can be constructed in a different way, and

the change of the-knitting depth can be performed by other means.
